I think the problem with it is that if we called it anything else, the Christians here wouldn't have the correct category. Atheism is related to religion; it can be called a view on religion (or more a view on a certain religious claim). I wouldn't call Christianity a "philosophical view" though.
If someone can think of a word that encompasses everyone then I'll be glad to change it.
